London, England 3 Claims. otat) This inventionrelates to insulatorapadsor the like forhelmets an'dfithe primary object of the invention is toprovide devices formed of resilient material which will act asinsulators between the inner portion or lining of the helmet and theouter shell thereof and at the same time assisting in locating the saidinner portion in position inside the shell. A further object is toprovide devices of such a construction that they can be fitted to thelining quickly and in a simple manner without employing metal or otherfastenings.

According to this invention, the insulator pad or the like is ofresilient material and comprises a body portion having a stud orprojection extending from its one face which stud is formed so as to beretained in a slot in a band or like portion of a lining.

The invention is particularly applicable to the insulators which aresecured to the lining within the helmet and which serve to locate samewithin the shell and according to this invention each insulatorcomprises a base portion of resilient material having a pad-likeprojection or head on its one face, and a stud or projection extendingfrom its other face, the said stud being formed so as to engage and beretained in a slot in a band of the lining.

For example, the said stud of each insulator comprises a resilient flatundercut member, the terminal portion thereof being of a size slightlygreater than the slot so that the terminal portion will pass through theslot and retain the insulator firmly in position.

The invention may also be said to comprise a lining for use in a crashhelmet, said lining comprising a head surrounding band and. twocrossover head bands, the said bands being provided with a plurality ofspaced apart elongated apertures, and a plurality of insulators ofresilient material, each said insulator consisting of a body portionhaving a head or projection from its one face towards its one end, and astud, one said insulator being fitted and retained on the band bypassing its stud through one f the said apertures.

In order that a clear understanding of the invention may be obtainedreference will now be made to the accompanying sheet of drawings,wherein:

Figure 1 is a fragmentary perspective View of a lining for use in aprotective helmet having preferred forms of insulators constructed inaccordance with this invention attached thereto,

Figures 2, 3 and 4 are side, end and plan views respectively of onepreferred form of stud for attachment to "the band of the lining adaptedto fit round the head, and v5 it .1 1 p Figure 5 is a plan view of apreferred form of stud for attachment to the band of the lining adaptedto fit over the head.

Referring to the drawing, the lining is of conventional form andincludes what may be termed a surrounding head band I, and twocross-over head bands, one of which, 2, is shown.

The insulator comprises a substantially rectangular strip like baseportion 3, said base portion having a head 4 which projects from its oneor outer face at one end. Upstanding from the other or inner face is anelongated stud-like member, comprising a shank portion 5 and a flatenlarged terminal portion 6. In the example illustrated in Figures 2, 3and 4, the stud like member is mounted with its longitudinal axistransversely of the longitudinal axis of the base portion 3 of theinsulator, while in Figure 5 the stud member is mounted with itslongitudinal axis on the same line as the longitudinal axis of the baseportion 3.

The head band I is provided with a plurality of four spaced apartelongated apertures I, and each cross over-head band 2 is provided witha plurality of two similar apertures, one near each end, each for thereception of the stud of one insulator. The slots of the band I arelongitudinally disposed therein while the slots of the band 2 aretransversely disposed.

In use, one insulator is retained in each slot by passing the studthereof through said slot, the insulator being retained in position byvirture of the size of the enlarged terminal portion of the stud thereofand its undercutting. The stud illustrated in Figures 2, 3 and 4 isfitted to the band I and the stud illustrated in Figure 5 is fitted tothe cross over bands.

The heads of the insulators bear against the inside of the steel or likeshell when the lining is secured in position within said shell.

The insulators are conveniently moulded in one piece from rubber.

I claim:

1. In a helmet insulating lining, a surrounding head band, a cross-overband connecting two opposite points on said head band and adapted topass over the top of the head, said bands being provided with mountingapertures, a plurality of resilient shock insulator members eachcomprising a resilient mounting stud formed integrally with saidinsulator member and projecting therefrom, each said stud comprising arestricted shank portion and further comprising an.

enlarged terminal portion conforming in shape to but slightly largerthan said mounting apertures for lockingly mounting said insulatormember on the outer surfaces of said bands.

2. In a helmet insulating lining, a head band adapted to surround thehead and provided with a plurality of elongated mounting aperturesextending longitudinally of said head band, a plurality of resilientshock insulator members each comprising a resilient mounting stud formedintegrally with said insulator member and projecting therefrom, eachsaid stud comprising a restricted shank portion and an enlarged terminalportion, each said shank portion being relatively flat and elongated andconforming in shape to but being smaller than said mounting aperturesfor readily passing through said apertures, each said terminal portionbeing elongated and conforming in shape to but being slightly largerthan said mounting apertures, for lockingly mounting said insulatormembers on the outer surfaces of said band.

3. In a helmet insulating lining, a surrounding head band, a cross-overband connecting two opposite points on said head band and adapted topass over the top of the head, said bands being provided with aplurality of elongated apertures, a plurality of resilient shockinsulator members each comprising a resilient mounting stud formedintegrally with said insulator member and projecting therefrom, eachsaid stud comprising a restricted shank portion and an enlarged terminalportion, each said shank portion being relatively flat and elongated andconforming in shape to but being smaller than said mounting aperturesfor readily passing through said apertures, each said terminal portionbeing elongated and conforming in shape to but being slightly largerthan said mounting apertures, for lockingly mounting said insulatormembers on the outer surface of said bands.
